The absolute best will be: 'He pressed the golden metal to his lips and whispered, "I am about to die."' Nothing can top that in my book, if executed correctly. But I have faith in Dan Radcliffe's acting skills.

But some scenes I am looking forward to as well:
- The forest duel
- King's Cross
- The final duel in Hogwarts
- The final Snape/Harry scene
- Snapes memories in the pensive
- McGonagall and D.A. in battle
- Harry casting the Crucio

Basically the end of the book - starting from when he arrives at Hogwarts up until the final duel. But not thge epilogue!
